Definitions
- the present invention relates to analgesic compositions for enhancing the efficacy and/or potency of certain opioid and non- opioid analgesics, that do not suppress blood coagulation, and have little hepatotoxic effect. More particularly, the present 10 invention relates to analgesic compositions that include analgesics referred to as the SCP series (SCP-1 through SCP-5) in combination with opioid and non-opioid analgesics.
- SCP series SCP-1 through SCP-5
- Drug combinations such as acetaminophen with codeine (Tylenol III) or acetaminophen with oxycodone (Lortab) produce analgesia that is additive or synergistic.
- the rational for using such combinations is to reduce the dose of each analgesic, and thus reduce adverse effects and toxicity, while retaining or
- acetaminophen has equal potency and efficacy to acetylsalicylic acid (aspirin) .
- acetylsalicylic acid aspirin
- NAPQI N-acetyl- benzoquinoneimine
- acetaminophen and a centrally acting analgesic may be even more dangerous than acetaminophen alone.
- these combinations require higher doses to produce the same analgesic effect because of an increase in tolerance.
- the safety of the drug decreases as the higher doses of the acetaminophen component increase hepatic and renal toxicity.
- n is a number from 1 to 5.
- the analgesic profiles of the SCP series are at least as good as that of acetaminophen. As expected, both types of drugs show little or no activity in the tail-flick and hotplate tests when compared with codeine.
- SCP-1 is more potent in the abdominal stretch, formalin, and Freund's adjuvant-induced inflammation assays of analgesia than acetaminophen. SCP-1 is lower in toxicity, and, of even greater importance, lower in hepatotoxicity (Paul et al . , 1998). All of these properties make SCP-1 and related derivatives potentially very useful pharmacologic agents.
- Figure 1 shows the analgesic effect of SCP-1 compared to codeine and acetaminophen.
- Figure 2 shows an isobologram for acetaminophen and codeine compared to an isobologram for SCP-1 and codeine.
- Figure 3 shows the hepatotoxicity of SCP-1 alone and in combination with codeine compared to acetaminophen alone and in combination with codeine in C57/bl6 mice.
- Analgesics by definition include drugs that through their action on the nervous system reduce or abolish the perception of pain without producing unconsciousness.
- analgesics fall into two broad categories: (1) simple, non-narcotic analgesics, such as aspirin, which appear to work by inhibition of prostaglandin synthetase, and (2) narcotic analgesics, which appear to work through interaction with the endorphin/enkephalin receptor system of the central nervous system.
- the term "narcotic" has historically been associated with the strong opioid analgesics, but the term is not very useful in a pharmacological context.
- narcotic analgesics can be further divided into two groups, the opioids and non- opioids .
- opioids refers to drugs with morphine like activity (agonists and antagonists) , acting on mu, delta and kappa receptors.
- non-opioids refers to drugs that act via a different mechanism.
- the drugs that comprise the group known as the opioid analgesics include among others the phenanthrene alkaloids of opium, comprising morphine, codeine, and thebaine. While thebaine produces no analgesia, it is an important intermediate in the production of semisynthetic opioids.
- agents with structures and function related to morphine include: (1) the morphine analogs, such as hydromorphone, oxymorphone, hydrocodone, and oxycodone; (2) Diels-Alder adducts, such as etorphine and buprenorphine; (3) the morphinan derivatives, such as dextromethorphan and butorphanol ; (4) the benzomorphan derivatives, such as phenazocine, pentazocine and cyclazocine; (5) the piperidine derivatives, such as meperidine and anileridine; and (6) open chain analgesics (methadone type compounds), such as methadone and propoxyphene .
- the morphine analogs such as hydromorphone, oxymorphone, hydrocodone, and oxycodone
- Diels-Alder adducts such as etorphine and buprenorphine
- the morphinan derivatives such as dextromethorphan and butor
- the drugs that comprise the group known as the non-opioid analgesics include: (1) N-methyl-D-aspartate (NMDA) receptor antagonists, such as dextromethorphan and ketamine and other antagonists that suppress central sensitization by competing for any of the binding site subcategories associated with the NMDA receptor, e.g., the glycine binding site, the phenylcyclidine (PCP) binding site, etc., as well as the NMDA channel; (2) alpha 2 adrenoreceptor agonists, such as clonidine, metomidine, detomidine, dexmetomidine, dexmedetomidine and xylazine, that reduce the release of norepinephrine; (3) other agents, such as tramadol, often mistakenly referred to as an opioid, that produce analgesia by their inhibitory actions on monoamine re-uptake rather than by agonist effect; (4) non-steroidal anti-inflammatory drugs such as
- Opioid and non-opioid analgesics may cause a variety of side effects including sedation, constipation, hypotension, nausea, vomiting, elevation of cerebrospinal fluid pressure, respiratory depression, physical dependence and tolerance. Therefore, there is a serious need to develop combinations of drugs that supplement the activity of the opioid and non-opioid analgesics, which allows the use of smaller doses of the opioid and non- opioid analgesics.
- One way of achieving this result is to enhance the analgesic activity of a known opioid or non-opioid analgesic by the addition of a second non-narcotic analgesic.
- the SCP series are non-narcotic analgesics that have little hepatotoxic effect .
- the compounds in this series do not produce the metabolite that is responsible for acetaminophen toxicity. As a result, they are more useful than acetaminophen and other non-narcotic analgesics in the treatment of chronic pain.
- the SCP series does not suppress blood coagulation. Children, the elderly and liver-compromised patients would also benefit from the administration of SCP for the treatment of pain.
- Pharmaceutical combinations utilizing the SCP series with opioid and non-opioid analgesics has been found to provide enhanced analgesia, without suppressing blood coagulation, and without the toxicity associated with conventional non-narcotic analgesics.
- the pharmaceutical combinations of the present invention comprise an opioid or a non-opioid analgesic in an intimate admixture with an analgesic from the SCP series along with a pharmaceutically acceptable carrier prepared according to conventional pharmaceutical techniques.
- Pharmaceutically acceptable carriers include solid or liquid fillers, diluents, and encapsulating substances .
- the amount of the carrier employed in conjunction with the combination is sufficient to provide a practical quantity of material per unit dose of analgesic.
- Pharmaceutically acceptable carriers for oral administration include, sugars, starches, cellulose and its derivatives, malt, gelatin, talc, calcium sulfate, vegetable oils, synthetic oils, polyols, alginic acid, phosphate buffer solutions, emulsifiers, isotonic saline, and pyrogen-free water.
- Pharmaceutically acceptable carriers for parenteral administration include isotonic saline, propylene glycol, ethyl oleate, pyrrolidone, aqueous ethanol, sesame oil, corn oil, and combinations thereof.
- Various oral dosages forms can be employed, including solid forms such as tablets, capsules, granules and bulk powders. Tablets can be compressed, tablet triturates, enteric-coated, sugar-coated, film-coated or multiple compressed, containing suitable binders, lubricants, diluents, disintegrating agents, coloring agents, flavoring agents, flow-inducing agents, and melting agents.
- Liquid oral dosage forms include aqueous solutions, emulsions, suspensions, and reconstituted solutions and/or suspensions.
- Pharmaceutically effective combinations can contain between 0.1 and 1000 mg of an analgesic from the SCP series.
- the preferred pharmaceutically effective combinations contain between 400 and 1000 mg of an analgesic from the SCP series.
- the pharmaceutically effective amounts of the opioid and non-opioid analgesics in combination with analgesics in the SCP series are similar to the corresponding combinations of opioid and non- opioid analgesics with acetaminophen.
- the following examples are illustrative of pharmaceutically effective combinations of the present invention:
- Dosage of SCP 100 - 1000

- the analgesic potency of SCP-1 is greater than that of acetaminophen in the abdominal stretch assay.
- the number of stretches exhibited by a mouse after an intraperitoneal (i.p.) injection of dilute acetic acid (Koster et al . , 1959) are counted.
- the analgesic compounds (acetaminophen, SCP-1, or codeine) were administered orally and fifty-five minutes later, the mice (groups of 8 or more) received an i.p. injection of 10 ml/kg of 0.4% acetic acid.
- the number of abdominal stretches was counted beginning 5 minutes after the acetic acid injection for a period of 10 minutes. For each of the compounds tested, the percentage of the number of stretches obtained in control animals (29 ⁇ 2.1) was calculated.
- an isobolographic analysis was performed to demonstrate the synergistic effect of an SCP- l/narcotic analgesic pharmaceutical combination.
- the isobologram is a quantitative method for measuring interactions between drugs where dose-effect relationships are depicted in a multidimensional array with lines connecting dose pairs that are equieffective in relationship to a common pharmacological endpoint .
- the isobolographic analysis permits a full range of doses and dose combinations to be examined where the proportion of the first drug to the second actually varies from 0 to infinity, and to determine, by virtue of the graphical display, whether any one or more of the paired drug combinations displays unique pharmacological properties in comparison to the entire body of generated data.
- the ED 50 for each drug was calculated using nonlinear regression analysis.
- a combination of acetaminophen and codeine or a combination of SCP-1 and codeine was tested using the same assay.
- the ratios of acetaminophen to codeine or SCP-1 to codeine were equivalent to the ratios of the ED 50 s of each drug alone.
- Dose-response curves for the drug combination ratios were produced and ED 50 s calculated.
- the ED 50 s were graphed according to the method of Tallarida et al . , (1997) . Briefly, the dose of one drug is depicted on the X-axis with a linear scale and a range of 0 to its ED 50 . The dose of the other drug is likewise depicted on the Y-axis. A line is drawn diagonally from ED 50 to ED 50 . This line is known as the line of additivity, as any combination of X and Y doses that fall upon this line would be predicted to produce 50% analgesia.
- the experimental ED 50 is plotted according to the dose of each individual drug and the standard error oriented on a line from the origin through the data point. Thus, when the ED 50 of the drug combination is plotted, any point (+ standard error) closer to the origin than the line of additivity would be considered to be synergistic
- the administered doses of acetaminophen and SCP-1 were equivalent to the acetaminophen LD50 in mice (3.7 mmole/kg) and the administered dose of codeine was 50 mg/kg.
